On the menu bar, go to Tools > Global Options.
Click Connection.
Global max connections/transfers
Choose the number of simultaneous connections you will allow from CuteFTP.
On a Windows 95/98/ME computer you can choose up to 40 connections.
On a Windows NT/2k/XP computer you can choose up to 200 connections, but CuteFTP will warn you that more than 20 connections may compromise system performance.
Connections include transfers, browse sessions, and every single thread in a Multi-Part transfer in CuteFTP Professional.
Per site max connections/transfers
Same as Global max but on a per site basis.
Note
If you choose to allow only one connection per site, you will need to transfer files over the browse session only (you will be able to navigate or transfer, but not both at the same time). This may be needed in situations where the server does not allow more than one connection from the same user. If the server allows more than one connection, then it is recommended that you use a value greater than one, for example 5. That way you can transfer files and at the same time continue to navigate the site.
Connection retry attempts
Choose the number of times CuteFTP can try to connect with a site before giving up. You can set CuteFTP to try connecting up to 1,000 times.
Delay between retries in seconds
Choose how long CuteFTP will wait before attempting a new connection after a failed connection. Choose up to 1,000 seconds (about 17 minutes).
Note
CuteFTP will not automatically retry upon fatal errors, such as a host unreachable (invalid IP address or host name), or upon receiving a socket 1006n error, which usually has to do with the client not being able to connect to the host for various reasons (firewall blocking, network error, host is down, etc.)
Connection timeout in seconds:
Choose how long CuteFTP will wait for an unresponsive server before it stops attempting a new connection. Choose up to 1,000 seconds (about 17 minutes).
E-mail address for anonymous logins
Enter the address you want to send to servers that require an e-mail address for anonymous logins. By default CuteFTP sends a simulated e-mail address.
Display the server's welcome message
Select this check box to display a pop-up window with information from the server when initial connections are successful.
Clear this check box to skip the server's successful connection message.
Send the FEAT command after login to determine feature support
Select this check box to ask the server for a list of extended features it supports.
Clear this check box stop sending the FEAT command, the server won't respond with a list of supported features.
Note
FEAT is used to determine whether extended features are supported, such as MDTM, MLST, and others. Not all servers support the FEAT command.
Send QUIT command before disconnecting
Select this check box to always send the QUIT command from CuteFTP no matter how you choose to disconnect.
Clear this check box to disconnect without sending the QUIT command.
Select this to use the UPnP NAT interface (available in Windows XP) to provide proper port-mapping when connecting securely from behind a NAT/firewall using PORT mode (rather than PASV, due to the remote host also being behind a NAT/firewall). Without UPnP, you would need to manually set the port range in the client and also enable and forward them in the NAT/firewall device.
Notes
You can choose Max connections, Delay between retries, and Retry attempts for individual sites. Highlight a site in the Site Manager, click File > Properties, click the Options tab.
